![]() ![]() The real interesting item is, being plugged into shore power a charger is generally running at 30 to 40 amps.Intellitec’s Bi-Directional Isolator Relay Delay – Diesel #00-00839-000 That much heat means a lot of power going somewhere, and the where is the real issue. Intellitec’s Bi-Directional Isolator Relay Delay – Diesel offers a new approach to charging batteries in an RV which uses an alternator. Adding a small dash-mounted switch will allow emergency starts of diesel engines, requiring up to 800 amps of starter current. Unlike proper systems that only allowed charging the RV battery from the engine’s alternator, the Bi-Directional Isolator Relay Delay – Diesel chargers both batteries when either one is being charged. When the coach is being driven, both batteries will be charged from the engine’s alternator. When the coach is plugged into shore power, both batteries will be charged from the converter. If neither battery is being charged, the batteries are fully isolated. The controller also senses heavy loads on either battery to prevent the wrong battery from being inadvertently discharged. The unit is housed in a plastic enclosure for mounitng in an engine compartment. To connect the two batteries together under proper conditions, it operates in combination with an intermittent duty solenoid, similar to ones used as diesel starter solenoids. ![]() In order to use this type solenoid for continuous duty, the controller will engage it with full voltage and then reduce the coil voltage to approximately 4 volts to hold it in. #HEAVY DUTY BATTERY ISOLATOR RELAY TROMBELLA FULL# The Intellitec’s Bi-Directional Isolator Relay Delay – Diesel operates by sensing the voltages on both batteries. When either battery is being charged, the controller will close the isolator solenoid, connecting the two batteries together, charging them both. #HEAVY DUTY BATTERY ISOLATOR RELAY TROMBELLA FULL#Īnytime either battery voltage goes above 13.3 volts for approximately 5 seconds, the solenoid closes.Operates In Combination With A Conventional Continuous Duty Cycle Isolator Relay That Has Been Used By A Number Of Vehicle Manufacturers Provides An Engine Driven Alternator With The Opportunity To Begin Charging The Main Battery Before Connecting The Auxiliary BatteryĪllows The Use Of Self-Exciting Alternators And Lets The Engine Briefly Warm Up Prior To Placing The Load Of A Heavily Discharged Auxiliary Battery On The Alternatorįully Encapsulated In A Plastic Enclosure For Mounting In The Engine Compartment With Two Screws When the ignition switch is turned off, the relay will open immediately.īi-Directional Isolator Relay Delay Offers A New Approach To Charging Batteries In An RV Application When this voltage goes above 13.3 Volts for approximately 12 seconds, as happens when the engine is running normally (normal alternator output voltage is approximately 14.4 Volts), it will close the isolator relay providing charging current to the auxiliary battery. It operates by sensing the voltage on the main 12 Volt system. There are three (3) wires to connect to the delay unit: one from an ignition switched 12 Volt source, a ground and the isolator relay coil. ![]() It operates in combination with a conventional continuous duty cycle isolator relay that has been used by a number of vehicle manufacturers. The unit is fully encapsulated in a plastic enclosure for mounting in the engine compartment with two screws. The unit is available in both 12 and 24 Volt versions. This allows the use of self-exciting alternators and lets the engine briefly warm up prior to placing the load of a heavily discharged auxiliary battery on the alternator. Unlike diode isolators, this system provides an engine driven alternator with the opportunity to begin charging the main battery before connecting the auxiliary battery. Intellitec’s Battery Isolator Relay Delay/E offers a low cost, reliable approach to charging multiple batteries. 00-00629-120 Intellitec Battery Isolator Relay Delay ![]()
